Kf Lab Calculate the following values for Trial 1. In all cases, show the calculations by expressing the number and a description of that number in parentheses. For example, for mass H2O,112.00g (mass NaCl+H2O ) 3.00g (mass NaCl)=109.00g (mass H2O). If these directions are not followed, no credit will be given. a) Moles of Sodium Chloride (moles) b) Mass of Water (kg) c) Molality of Sodium Chloride Solution (mol solute/kg solvent)
